SAFETY-BOTTLE.

Specification of Letters Patent.

Patented Jan. 1, 1907.

To all whom, it may concern:

Be it known that we, WILHELM WIEGAND and ALFRED BRAUNERSREUTHER,subjects of the German Emperor, and residents of the city, county, andState of New York, have invented certain new and useful Improvements inSafety-Bottles, of which the following is a clear, full, and exactdescription.

This invention relates to safety bottles or receptacles, the objectbeing to provide a simple means which can be inserted into the neck oroutlet of a gaseous-liquid receptacle, such as a bottle, which willautomatically open and relieve the pressure of any excess gases whichmay be generated therein.

Our improved safety device is particularly adapted for receptaclescontaining gas-producing liquids, it being so organized as to open andrelieve the pressure of the excess gases when said pressure reaches adangerous or predetermined point, whereby explosion of the receptacle isavoided.

To these and other end, which will hereinafter appear, our inventioncomprises the novel features of improvement, combination, andarrangement of parts, which we will now proceed to describe inconnection with the accompanying drawings, forming part hereof, whereinFigure 1 is a vertical central section of the neck and a portion of thebody of a bottle containing our improved safety device, the valve beingshown in elevation. Fig. 2 is a plan view thereof. Fig. 3 is a sectionalplan view thereof, the section being taken on a line a a in Fig. 1. Fig.4 is a bottom plan view of the cap. Fig. 5 is a sectional diagrammaticplan view taken through the cap, showing the manner of applying the capto the neck of the bottle; and Fig. 6 illustrates, on a reduced scale, avertical central sectional view of our improvements, wherein anadjustable nipple is shown applied to the cap, the valve being shown inelevation.

Similar characters of reference are intended to indicate correspondingparts in the several views.

Referring to Fig. 1 of the drawings, the numeral 1 indicates a portionof the body of a bottle, which has extending therefrom the neck 2. 3indicates a valve-seat, preferably formed integral with the neck 2. Inorder to close the opening 4 of neck 2, we employ a valve 5, which is inthis instance illustrated as spherical, but same may be of otherformation. The valve 5 has extending therefrom a stem 6, which isprovided in the periphery thereof with an annular groove 7. Said valveand stem are preferably formed of an integral piece of glass. The neck 2of the bottle is provided at the top thereof with outwardly-extendingflanges 8 8, oppositely disposed, the edges 9 of said flanges beingcurved concentric with the periphery of the neck 2 and the sides thereofbeing tangent to said neck, as shown in Fig. 3. To seal the outlet 10 ofneck 2, we employ a cap 11, provided with inwardlyextending flanges 1212, the distance between said flanges being slightly greater than thediameter of the neck 2 (see Fig. 5) and less than the diameter .of thecurved edges of the flanges 8 8. The cap 11 is perforated, as at 13, theperforation or opening being fitted with a nipple 14, which extendsinwardly, as shown, Fig. 1. 15 indicates a coiled spring, which at itslower end is sprung into the groove 7 and at its upper end is passedover the nipple 14 and soldered or otherwise attached to the cap ornipple. It will thus be seen that when the cap 11 is removed the valve 5and spring will come with it. Between the cap 11 and top 16 of the neck2 we insert a washer or gasket C of suitable material. As the stem 6 ofthe valve 5 is smaller than the inner diameter of the spring 15, saidvalve can accommodate itself to the valve-seat 3 in obvious manner.

In order to fill the bottle, the cap 11 is removed, the valve 5 andattached spring 15 being at the same time withdrawn. After having filledthe bottle with gaseous liquid the valve 5 is inserted into the neck ofthe bottle, and the flanges 12- 12 of the cap 11 will then be passedover the edges A of the flanges 8 8, Fig. 5, until the top of the cap 11contacts the gasket 0, said gasket being thick enough to require aslight pressure thereon before the flanges 12 12 can be forced under theflanges 8 8. After having gotten the cap 11 in the aforesaid position aslight downward pressure is then applied and the cap turned to the rightor left until the flanges 12 12 look under the flanges 8 8, Fig. 3. Inthe meantime the valve 5 will have been pressed home against the seat 8by the spring 15. The spring 15 not only offers a resistance to theordinary pressure from within the bottle, butalso tends to retain thecap 11 in position with respect to the lockingflanges referred to. Thetension of spring 15 will be sufficient to hold the valve closed againstthe flow of the liquid, thus acting as a stopper, but will permit thegases generated within the bottle to escape around the valve and outthrough the nipple 14 when the pressure of the said gases overcomes thetension of the spring 15.

Figure 6 shows the cap 11 fitted with an adjustable threaded nipple 17,the flange 18 thereonserving to retain the spring 15. By screwing thenipple in or out the tension of the spring can .be adjusted, whereby agreater or lesser pressure of the gases will be required to open valve5.

Having now described our invention, what we claim, and desire to secureby Letters Patent, is

1.. In combination with a liquid-receptacle provided with an outlet,said outlet being provided with a valve-seat, a valve having anelongated stem and adapted to impinge upon said valve-seat, a coiledspring encircling said stem and adapted to press said valve against saidseat, a cap for said outlet havin an o enin a tube communicatiiw' b 37 Owithsaid opening and adapted to retain the spring in position.

2.. In combination with a liquid-receptacle provided with an outlet,said outlet being provided with a valve-seat, a valve having a stemandadapted toimpinge upon said valveseat, a coiled springencircling saidstem and adaptedto press saidvalve against said seat, a self-sealing.cap for said outlet, said cap having an opening, and a nipplecommunicating with said-opening.

3. A bottle having upon the neck thereof outwardly-extending flangesoppositely disposed, a perforated :cap for said neck provided withinwardly-extending flanges adapted to engage the under side of saidflanges whereby said cap is retained in place, a valveseat in said neck,a valve in said neck adapted :to impinge upon said valve-seat, and aspring retained by said cap adapted to force said valve against itsseat.

4:. A bottle having .a neck provided with a plurality of projections,combined with a cap provided with means adapted to engage said wherebysaid cap is retained in place, a valveseat in said neck, a valve in saidneck adapted to impinge upon said valve-seat, said valve being providedwith an elongated stem, a coiled spring adapted to fit over said stemand force said valve against its seat, and an adjustable nipple carriedby said cap adapted to retain said spring and adjust the tensionthereof.

6. A safety device adapted for receptacles containing gaseous liquids,comprising a valve adapted to normally close the outlet of saidreceptacles, said valve being provided with a stem, said stem having anannular groove in the periphery thereof, a coiled spring adapted tosurround said stem and engage said groove, a cap for said outlet, saidcap having said spring attached thereto, whereby said valve can beremoved simultaneously with said cap, and an outlet above said valve forthe escape of the generated gases.

7. A bottle having a neck, a valve-seat therein, a valve adapted toimpinge against said seat, a cap removably fitted upon said neck, acoiled spring secured at one end to said valve and at the other end tothe cap, and means for regulating the tension of said spring.

8. A bottle having a neck, a valve-seat therein, a valve provided with astem fitting in said seat, a cap removably fitted upon said 'neck, thecap provided with an opening, a

threaded nipple fitting in said opening, and a coiled spring securedtothe stem of said valve and to said nipple.
